Crew and cabin were very good. Movies were mostly old or very old (wizard of oz, gone with the wind). Knee room is a bit short, but not horrible.

10.0 ExcellentDon, Jul 2026

Crew and cabin were very good. Movies were mostly old or very old (wizard of oz, gone with the wind). Knee room is a bit short, but not horrible.

It was great. I had an exit row seat so I had a ton of legroom. The service was good and the food was decent.

Aircraft used was a 10 year old 767 which is being maintained in excellent condition. Business class was very comfortable and reclined sufficiently to allow me to sleep. The crew were excellent and very attentive. The only two unfortunates were a) food quality, the beef was very tough and below the standard for business class service; and b) the onboard entertainment offered little for non-Mongolians. All around, I would gladly fly MIAT again.

The flight was on time and the aircraft new and well-maintained. Service was friendly and well carried out. Seating on the 737 MAX in business class was comfortable enough that I could doze off during the 4 hour flight. Arrival in Ulsan Baatar was on time and baggage delivered to the belt quickly. I was pleasantly surprised by the entire event and have no trouble recommending MIAT.

No entertainment display working whole flight it was like a veggie 😒

Excellent. All well and accommodating. Clean and very good food. Peaceful travel experience

The food wasn't to good but the crews were great, clean plan clean bathrooms always

Always on time and flight crew were great. Boarding in Manila was a bit chaotic and disorganized compared to Incheon.

Never had a flight delay issue with Korean Air, that's why I always go with this airline.

Flight crew were very attentive and made this trip a pleasure. Plus the fact that this our first time flying business class.

The boarding process was efficient and quick. The seats were comfortable. The food was good. The service was excellent. We had a lovely flight from Seattle on Korean air

Flight crew was fantastic. The aircraft was meticulously cleaned at all times. The crew was continuously checking to see if the passengers were ok.

Korean are so racist and when I ask question or directions they totally ignore me and say racist. Also they give me an rude attitude.

It was good, I liked the self-serve snacks but it was a little difficult to get the alcohol, which is understandable since I wouldn't want kids sneaking it.

Friendly flight attendants and gate agents. Very clean plane and food was good!

Not enough seat cushion. Butt was hurting especially on long flight. Not enough movie selection. Entertainment was outdated. Coffee served was cold. Other than that flight was good.

I was very surprised that a meal was given on such a relatively short flight. the meal was FANTASTIC. The crew were also very attentive to our specific needs and we would be happy to fly and recommend your airline to our friends.

Humm, I should have known that the seat I peaked on my flight from Inchon to Manila was designed for a toddler or very small person.

The staff hold my luggage to steel and exchange my stub, i was very disappointed.

Kayak along with airfare assay are attempting to steal my money. Charges are being pressed.

Customer service and attention to details. The food was good.

Felt like the oldest plane in Asiana Fleet. Screen was 5-6in only and no charging at all. Movie selection wasn't great.

I’d have rated Asiana good except an unfortunate incident in which I felt one of your employee didn’t really help us. During the first leg of the trip, the flight from LAX to ICN, I left my backpack on the plane. When I realized, I reported to one of your employee who promised me that it’d be taken care of, that my backpack will be there at HCM city. When we arrived there, HCM people had no idea and my backpack was still at Incheon airport who denied any knowledge whatsoever. I was left in the cold and felt helpless. I was very disappointed. I’d like someone to look into this and let me know.

It was my first time flying Asiana but i was very pleased with how professional and understanding the flight crew is with little kids. One flight attendant held my 3 year old daughter’s hand guiding her to the exit after landing while i had my hands full with luggage and my infant. She was very helpful.

30 minutes from landing in Mongolia we had to turn around and go back to Korea due to a storm in the capital of Mongolia. We went back the following day. Safety first!

Tightest knee space ever experienced on any budget airline. Crew polite and efficient, take off and arrival on time. Surprised that they did not offer water on flight except as sales product. Questions about Food and entertainment not applicable since neither are offered.

At the boarding gate, Jeju airline accepted "carry on" bags for checking in for free due to the "limited cabin space". This is because most passengers were carrying multiple bags that exceed the size and weight limit for carry on items. Rather than inspecting carry-on bags at the counter and requiring excess bags to be checked in for a fee, they allowed freeloading at the boarding gate to to the detriment of those who paid the fee for checked bags. This is totally unfair.

As posred earlier the crew was very accommodating & professional. Thank You Allen

All though you can not help it the kids was loud and unruly, The crew was very accommodating and professional. Thank You Allen.

No priority counter check in for families with young children.

The flight was delayed from GUM to ICN, there was no notification on how delayed the flight would be. Although we received notice, there was no specified time given. The flight was also very uncomfortable.

Nothing as both flights have been cancelled a few days before departing. All trip has to be rescheduled and the net cost is above 500 US$. There is nothing positive wit AEROMONGOLIA. Alain Rougier
